Changeset 37573 for trunk/src/wp-admin/includes/taxonomy.php

Message:

Store only term IDs in object term relationships caches.

Previously, objects containing all data about a term were stored in each
object's term cache. Besides being wasteful, this approach caused invalidation
issues, as when a modified term count required a flush for all objects
belonging to the term.

Backward compatibility is maintained for plugins that continue to put object
data directly into the {$taxonomy}_relationships cache bucket.

Fixes #36814.
